Deep-sea Core From Okinawa Trough Gives 200,000-year Environmental History Of Continental Shelf
2013-09-26 09:38:37

Science China Press A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough. It is tesitfied that the continental shelf of the East China Sea was exposed and covered with the huge wetland and grassland ecosystems during the the last two glacial periods. They discovered that the variation of terrestrial sources is concordent with global glacial volume and sea-level changes at...

Greenland Ice Core Research Points To Higher Seas, Warmer Past
2013-01-24 11:07:31

Brett Smith for redOrbit.com - Your Universe Online New research findings based on Greenland ice cores show that if climate change patterns repeat themselves, the Earth will become much warmer and sea levels will rise significantly. In a new report published in the latest edition of the journal Nature, scientists have used Greenland ice cores over 1.5 miles long to collect data on the Eemian period, around 115 to 130 thousand years ago. An analysis of the cores allowed the international...

More Than A Million Years of Climate History Revealed
2012-08-10 13:25:58

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Cambridge Department of Earth Sciences has successfully reconstructed temperature from the deep sea to reveal how global ice volume has varied over the glacial-interglacial cycles of the past 1.5 million years. The study, "Evolution of ocean temperature and ice volume through the Mid-Pleistocene Climate Transition," reported in the journal Science, announces a major breakthrough in understanding...

Climate In Arctic More Vulnerable Than Thought

First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million...

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

Deep sediments are unparalleled record of biotic changes over past 200,000+ years University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population. The lake sediments are among the world's oldest, containing records of biological change stretching back as far as 500,000 years. The core...

Caltech Researchers Use Stalagmites To Study Past Climate Change
2012-05-04 05:39:29

There is an old trick for remembering the difference between stalactites and stalagmites in a cave: Stalactites hold tight to the ceiling while stalagmites might one day grow to reach the ceiling. Now, it seems, stalagmites might also fill a hole in our understanding of Earth's climate system and how that system is likely to respond to the rapid increase in atmospheric carbon dioxide since preindustrial times. Many existing historical climate records are biased to the high latitudes–...

Image 1 - New Coral Dating Method Gives Hints Of Possible Future Sea-level Changes
2011-09-12 07:29:54

  New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, says a research team led by the Woods Hole Oceanographic Institution (WHOI). In a paper published online in the Sept. 11 Nature Geoscience, the researchers report data from an improved method of dating fossil coral reef skeletons in the Bahamas. By calculating more accurate ages for the...

Scientists at the University of York, using an 'amino acid time capsule', have led the largest ever program to date the British Quaternary period, stretching back nearly three million years. It is the first widespread application of refinements of the 40-year-old technique of amino acid geochronology. The refined method, developed at York's BioArCh laboratories, measures the breakdown of a closed system of protein in fossil snail shells, and provides a method of dating archaeological and...
